Supermicro-Certified 64GB DDR4 RDIMM

This 64GB DDR4 2933MHz registered ECC module is built for Supermicro servers that require validated memory. It targets administrators who need guaranteed compatibility and error correction for mission-critical workloads.

Registered 288-Pin Design for Server Boards

The RDIMM form factor uses a 288-pin connector and registered buffering to reduce electrical load on the memory controller. Dual-rank 2Rx4 organisation allows higher density per slot while maintaining signal integrity in multi-DIMM configurations.

64GB Single-Module Capacity

A single 64GB stick delivers large memory capacity in one slot, enabling high total system memory on boards with limited DIMM slots. Buyers needing smaller increments or non-ECC unbuffered memory for workstations should look elsewhere.
